  1. Cellular Phone and Data Standards Past, Present, and Future

  2. 1G Phone and Data Standards • Voice • AMPS - Advanced Mobile Phone System • Data • CDPD - Cellular Digital Packet Data • Mobitex • DataTac

  3. AMPS - Advanced Mobile Phone System • Analog Network • Uses Frequency Division Multi-Access • 800 MHz • Low security • CDPD for data • Verizon and Alltel still operate networks

  4. CDPD - Cellular Digital Packet Data • Utilizes unused AMPS phone bandwidth • Up to 2.4 KB/s • No active networks

  5. Mobitex • Data only • 900 MHz • Max of 1 KB/s, Avg 500 Bytes/s • Two way pagers, wireless email, Original Blackberry and PDAs

  6. DataTac • Data only • 800 Mhz • Up to 2.4 KB/s • Used in Two way pagers and Original Blackberry devices

  7. 2G Phone Standards • D-AMPS – Digital AMPS • iDen – Integrated Digital Enhance Network • GSM – Global System for Mobile Communications • IS-95 or CDMA

  8. Digital AMPS • Digital Network • Utilizes existing 800 MHz AMPS channels • Uses Time Division Multi-Access • 3 Times the call capacity over AMPs • SMS and CSD (Data)

  9. iDEN – Integrated Digital Enhanced Network • Digital Network • 800 MHz • TDMA • SMS, Push to Talk, SIM cards, and WiDEN (Data) • Fastest PTT response time • Nextel operated network

  10. GSM - Global System for Mobile Communications • Digital Network • 850 MHz and 1900 MHz • TDMA • Most used standard today • SMS, SIM cards and later PTT • Data thru CSD, GPRS, EDGE • Cingular and T-Mobile operate networks

  11. IS-95 CDMA • Digital • Uses Code Division Multi-Access • Not widely used in US • Father of CDMA2000

  12. 2G Data Standards • WiDEN - Wideband Integrated Dispatch Enhanced Network • CSD - Circuit Switched Data • HSCSD - High-Speed Circuit-Switched Data • GPRS - General Packet Radio Service • EDGE - Enhanced Data rates for GSM Evolution

  13. WiDEN - Wideband Integrated Dispatch Enhanced Network • Operates over iDen • Communicate on up to 4 channels • Up to 12.5 KB/s on all 4 channels • Nextel operated network

  14. CSD and HSCSD • Operates over GSM • CSD uses 1 time slot for 1 KB/s • HSCSD uses 4 time slots for 7 KB/s • Dedicated circuit when connected • Billed by time connected • T-Mobile and Cingular limited availability

  15. GPRS - General Packet Radio Service • Utilizes unused GSM phone bandwidth • Up to 4 time slots • Speeds 3.75 KB/s – 10 KB/s • Shared connection with everyone in cell • Billed by amount of data moved • T-Mobile and Cingular

  16. EDGE - Enhanced Data rates for GSM Evolution - EGPRS • Enhancement for GPRS • Theoretical max of 8 timeslots • Speed of 30 KB/s on 4 slots • T-Mobile and Cingular

  17. 3G Standards • Transfer Voice and Data Simultaneously • CDMA2000 • CDMA2000 1X • CDMA2000 1X EV-DO • CDMA2000 1X EV-DV • WCDMA – Wideband CDMA • UMTS

  18. CDMA2000 • Family of 3G standards • CDMA2000 1x • CDMA2000 3x (Not used) • CDMA2000 EV-DO • CDMA2000 EV-DV (Not used) • Uses CDMA • Each handset xmits unique code • Handsets share same frequencies

  19. CDMA2000 1x • Most basic • Max speed of 18KB/s • Verizon, Sprint, and Alltel

  20. CDMA2000 1x EV-DO Evolution Data Optimized • Evolution of CDMA2000 1x • Revision 0 currently deployed in US • Max D/L of 320 KB/s • Max U/L of 77 KB/s • Revision A • Max D/L of 396 KB/s • Max U/L of 230 KB/s • Verizon and Sprint limited markets

  21. WCDMA – Wideband CDMA • CDMA Network • Spread Spectrum

  22. UMTS - Universal Mobile Telecommunications System • Successor to GSM • Uses WCDMA for Air interface • Uses 850 MHz and 1900 MHz • HSDPA and HSUPA for Data • Cingular limited markets

  23. HSDPA - High-Speed Downlink Packet Access • Part of UMTS • Speeds of 460 KB/s down and 230 KB/s up • Future plans for 920 KB/s speeds • Cingular in limited markets

  24. HSUPA - High-Speed Uplink Packet Access • Offers great upload speeds • Max Upload speed of 740 KB/s • Cingular to do Field Testing by end of 2007
